T0 all whom it may concern.'

Be it known that I, J oHN l". OConivon, a citizen of the United States,residing at Chicago,lin the'county of'Gook and State of Illinois, haveinvented a certainA new `and useful Improvement "inSide Bearings forRailway-Cars, of which the following is a full, clear, concise, andexact description, reference being had to the "accompanying drawin'tion. y y

My invention relates to improven'ients in side bearings for railwaycars.

Vlfhe object ofmyinvention is to provide an eiiicient laterallyadjustable sidebearing.

In the drawings forming `a part of this specification, Figure 1 isa sideelevation of a side bearing `embodying my invention; Fig. 2 is a crosssection taken on line 2-2 of Fig. 1 g `Fig. Slis a cross Asectiontakenon line 8-3 of Fig. 1.

Referring to the drawings, the numeral 10 indicates one of the holstersof a railway car shown in cross section, as, for instance, the upper orbody bolster, and 11 refersl to the opposed Vbolster shown in crosssection, as, for instance, the lower or truck bolster. The side bearingis indicated at 12, and comprises a base member 13 adapted to be se,-cured to one of the bolsters, as, for instance, the body bolster 11, bymeans of the fianges 14 provided thereon and the rivets 15. The basemember is of a general hollow box-like shape, open on its upper side 16,and when applied to a bolster is provided with the lower lateralopenings'l'? to permit the passage of dirt, cinders or other foreignmaterial. rIhe base member is provided near each of its ends with thebearings 19-19 to receive the journals 20 with which the ends of each ofthe spherical rollers 21 are provided. Near its ends the base member isprovided upon either side with the upstanding brackets 22-22 betweenwhich the movable bearing plate 23, which is longitudinally extended inreference to the base member, is designedto operate. The said bearingplate has upon its under surface the arcuate bearing face 24 designed toride upon the spherical rollers 21. Intermediate its ends the movablebearing plate 23 is provided with the lateral flanges 25 perforated asat 26 for the passage of a spring bolt 27 Vwhich passes through thebrackets 22, the

said bolt being provided with Va head 28' at gs, forminga part of thisspeciica-` oneend anda Vnut'29at the other endthe head and nut being onthe outer facesofthe brackets with which `they areW associated, each ofsaid spring bolts 27 bearing a spring 30, "the said springs 30 being"seatedbetween the flange 25 at one end andagainst oneof the brackets atthe otherend. The perforations inthe brackets 22 jor `flange 25 for thepassage of thespring bolt 27 vare en-` larged fpreferably at the pontfofpassage through theflange25, as indicatedby `the dotted lines referenced31 in 'F 1 of the to permit the `lateral `oscillation ofV drawing, thebearing plate "Theupper `face"32of the bearing plate is adapted tobeengaged by the"opposedbolster, as, for instancathe bolster 10, andupon 'such engagement the movable piatte 23 rides longitudinally bf thebase member, friction being prevented "throughthe rotation ofthe`rollers 21. :Upon any relative deflection of the holsters, the upperface of the movable bearing plate 23 is adapted to oscillate laterallyto date its bolster bearing face 34 to the opposed bolster by reason ofthe arcuate form of its lower face which rides upon the sphericalrollers 21.

In its normal position, the plate 23 is as shown in Fig. l of thedrawings, but upon longitudinal movement in either direction the springs30 against which it moves are compressed between the flange 25 and thebracket 22 against which the compressed spring is seated at the otherend, so that upon release of the bearing plate and its opposed bolsterthe springs will return the bearing plate 23 to its normal position.

I claim:

1. In a side vbearing base member, a bolster to which the base member issecured, an opposed bolster, a

for railway cars, a

bearing plate adapted to engage said opber, bearing V'plate associatedlwith said roller, the said bearing plate having an arcu# ate'face'engaging said roller and having both longitudinal andy lateralmovement upon said roller.

l. In a side bearing forrailway cars, in combination; a'base member, aroller comprising a sphere and journals mounted in said base member, abearing plate mounted upon said roller, the said bearing plate having'anarcuatefface engaging the roller and havingboth longitudinal and lateralmovement upon said roller.

,5.A In a side bearing for railway cars, a base member adapted to besecured toa bol- .'ster, a bearing plate Vassociated With said with thebase member adapted to engage the opposed bolster, the base member beingprovided with brackets forming spring seats, springs for said seats, thebearing plate having a member engaging said springs, the base memberbeing further provided With rollers, the rollers having a sphericalface, the bearing plate having an arcuate surface engaging the rollerswhereby the said plate may move longitudinally and laterally upon saidrollers.

7. In a side bearing for railway cars, in combination: a base member,brackets at the end of said base member, rollers revolubly mounted inthe base member, a bearing plate associated with said rollers, aspringbolt a url springs, the bearing plate being provided with aflange, springs being mounted between said {iange and the brackets uponthe base member, the rollers having a spherical poi'- tion, the bearingplate having an arcuate bearing face adapted to engage the rollerswhereby the bearing plaie may move laterally and longitudinally uponsaid rollers.

In Witness that .l claim the foregoing l have hereunto subscribed myname this 26th day of May, 1917.
